In Indian film music, which playback singer sang the popular song Jag Ghoomeya from the Bollywood movie Sultan starring Salman Khan and Anushka Sharma?

Introduction / Context:
Bollywood films often become famous not only for their stories but also for their songs. Sultan, a sports drama starring Salman Khan and Anushka Sharma, featured the romantic track Jag Ghoomeya, which became very popular with audiences. General awareness questions about Indian cinema frequently ask who sang a particular hit song, and in this case, the focus is on identifying the playback singer of Jag Ghoomeya.

Given Data / Assumptions:
- The song title is Jag Ghoomeya.- The film is Sultan, a major Bollywood release.- Options list Sonu Nigam, Shaan, Rahat Fateh Ali Khan, and Arijit Singh.- We must pick the correct playback singer responsible for the well known version of this track.

Concept / Approach:
The main and most recognised version of Jag Ghoomeya in Sultan is sung by Rahat Fateh Ali Khan, a renowned singer known for his soulful and Sufi influenced style. While Arijit Singh and other singers also recorded versions or covers of the song, it is Rahat Fateh Ali Khans rendition that is associated directly with the movie and promoted as the key soundtrack version.

Step-by-Step Solution:
Step 1: Recall the soundtrack credits of Sultan, especially for Jag Ghoomeya.Step 2: Among the listed singers, Rahat Fateh Ali Khan is widely known for providing vocals to many intense romantic and Sufi style songs for Hindi films.Step 3: Sonu Nigam and Shaan are prominent playback singers but are not credited with the main Jag Ghoomeya track in Sultan.Step 4: Arijit Singh has sung many romantic songs in the same era, which can confuse candidates, but he is not the main singer for this particular song in the film.Step 5: Confirming the film credits shows that Rahat Fateh Ali Khan is the playback singer for Jag Ghoomeya in Sultan.

Verification / Alternative Check:
Checking the official soundtrack listing of Sultan or credible music platforms clearly shows that Jag Ghoomeya is sung by Rahat Fateh Ali Khan. Promotional materials, music videos, and most media reviews also mention his name in connection with this track, removing any lingering doubt.

Why Other Options Are Wrong:
Sonu Nigam: A celebrated playback singer in his own right, but not the voice behind Jag Ghoomeya in Sultan.Shaan: Known for many romantic songs and television roles, yet not credited for this particular song.Arijit Singh: Extremely popular for modern film songs, but not the main playback singer for Jag Ghoomeya, even though his name may appear in some alternate or promotional versions.

Common Pitfalls:
Because Arijit Singh has sung many romantic hits in recent years, some candidates reflexively select his name when they see a love song in a contemporary film. Another pitfall is failing to associate Rahat Fateh Ali Khans distinct vocal style with specific songs, even though his name is very prominent. To avoid such mistakes, aspirants should revise the soundtracks of major movies and link them with the correct singers.

Final Answer:
Rahat Fateh Ali Khan is the playback singer who sang Jag Ghoomeya in the film Sultan.
